fiber made from the fleece of the domestic sheep. Composition and Characteristics

Wool consists of the cortex, overlapping scales (sharper and more protruding than those of hair) that may expand at their free edges causing fibers to intermesh; elasticum, the

 formed by shearing a sheep in one continuous operation. The average fleece weighs from 5 to 10 lb (2.3–4.5 kg); in highbred wool sheep such as the American Merinos a ram's fleece may reach 30 lb (13.6 kg). The weight lost in cleansing the fleece of grease before sorting the wool is called shrinkage. On large sheep ranches hand shearing, once a competition skill, has largely been replaced by machine shearing. In heraldry a fleece is a whole, stuffed ram's fleece, complete with head and feet, suspended by a band around its middle. See also Golden FleeceGolden Fleece,
in Greek mythology, the magic fleece of the winged ram that saved Phrixus and Helle, the children of Nephele and Athamas, from the jealousy of Ino, Athamas' second wife.

Fleece

 

wool removed from a sheep in an entire layer. Fleece consists of staples or locks of wool that are held close to one another by connecting wool threads in homogeneous wool and by the bunching of down at the bases of the locks in heterogeneous wool. The fleece is removed in the spring from fine-wooled, semifine-wooled, semicoarse-wooled, and coarse-wooled sheep. Autumn and lamb’s-wool shearings do not form a fleece but fall into separate pieces. The wool covering on sheep before shearing is also called fleece.

Although, goats have been traditionally one of the major sources of red meat in Iran (102,000 ton per year), however there are limited published results on the estimates of genetic parameters for growth traits and yearling fleece weight in Markhoz goats.
Measurements were taken on body weight performance at birth (BW), weaning (WW) at about three month of age, six month (6MW), nine month (9MW), yearling (YW) and on fleece weight at yearling age (YFW) of kids.
Multivariate analysis results obtained for estimates of direct additive genetic correlations, maternal additive genetic correlations, maternal permanent environmental correlations, phenotypic and environmental correlations between body weight at different ages and yearling fleece weight are given in Table 4.
The least square mean for yearling greasy fleece weight was lower than those reported for Angora goat by Yalcin et al.
The effects of non genetic factors indicated that performance records for body weight at different ages should be corrected for effects of sex, type of birth, age of dam, year of birth and age of kids at WW, 6MW and 9MW, but for yearling greasy fleece weight only correction for effect of year is needed.
